Description:

GENUS AND SPECIES

[0001] Rhododendron sp.

VARIETY DENOMINATION

[0002] `MNIHAR010`

[0003] BACKGROUND OF THE NEW PLANT

[0004] The present invention is a new and distinct variety of evergreen
Azalea of the genus Rhododendron. This new Azalea, hereinafter referred
to as `MNIHAR010`, was discovered in 1985 in Lawrenceville, Ga.
`MNIHAR010` originated from a planned cross hybridization between the
female azalea plant `Cherie` (also known as `V12-4`) (unpatented) and the
male azalea plant `Indian Summer` (unpatented) in a controlled
environment in Lawrenceville, Ga. The present invention has a unique
blooming period, growth habit, and cold hardiness.

[0005] Asexual propagation of the new plant by semi-hardwood cuttings was
performed at a nursery in Dearing, Ga. The new plant retains its
distinctive characteristics and reproduces true to type in successive
asexual propagations by semi-hardwood cuttings.

SUMMARY OF THE INVENTION

[0006] The following are the most outstanding and distinguishing
characteristics of this new cultivar when grown under normal
horticultural practices in Dearing, Ga. [0007] 1. Spring and fall
blooming; [0008] 2. Attractive, showy, dark pink flowers; [0009] 3.
Numerous single and semi-double flowers; [0010] 4. Easily propagated by
semi-hardwood cuttings in late spring through summer; [0011] 5. Fast
growth rate under normal fertilization and moisture conditions; [0012] 6.
Upright, dense, and compact nature; [0013] 7. Grows well in containers;
[0014] 8. Thrives in shade or sun; and [0015] 9. Hardy in Zone 6.

DESCRIPTION OF THE PHOTOGRAPHS

[0016] This new Azalea hybrid variety is illustrated by the accompanying
photographs which show buds, flowers, immature foliage and mature
foliage. The colors shown are as true as can be reasonably obtained by
conventional photographic means. The photographs are of plants that are
4-years old, grown in three-gallon containers in October in 2009 in
Dearing, Ga.

[0018] FIG. 2 is a close-up showing flower buds and immature foliage.

[0019] FIG. 3 is a close-up showing flower size, form, and color.

DETAILED BOTANICAL DESCRIPTION OF THE NEW PLANT

[0020] The following is a detailed description of the new variety of
Azalea based on observations made of 4-year-old plants grown in a
three-gallon containers according to wholesale commercial production
conditions under full-sun and in an evaluation bed under semi-shade
conditions in Dearing, Ga. in spring, summer, and fall in 2009. The
colors of the various plant parts are detailed with reference to The
Royal Horticultural Society Colour Chart (2001). [0021] Classification:

Culture: `MNIHAR010` grows well in a wide range of conditions and
tolerates sun to shade. `216I` prefers moist, well-drained soil that is
rich in organic matter and responds well to mulching and medium
applications of fertilizer. `MNIHAR010` does best in soil with a pH of
5.0 to 5.5 and is propagated with semi-hardwood cuttings in late spring
through the summer Azaleas root in five to six weeks with high 80% plus
percentage of rooting, tissue culture is also an effective means of
propagation for azaleas. [0084] Diseases and insects: Lace bugs, root
weevils, and spider mites can be a problem. Fungal and bacterial
pathogens have not been observed, but no resistance testing has been
performed and no claim to abnormal resistance to pathogens can be made.
[0085] Comparison with parental and commercial varieites: In Table 1, the
`MNIHAR010` is compared to parental varieties `Cherie` (unpatented) and
`Indian Summer` (unpatented) and lists the differences between the
varieties.
